• AD8497 with mux

    Can I put an analog mux in front of an AD8497 to read multiple thermocouples with one device?

  • ad8497 pull-up

    We have 8 channel MUX on the input to the AD8497.

    In order to improve response time we have added the TC filter for open each TC before mux.

    This open TC 10M resistor connects to 5V, is this 5V connection ill-advised given the in+ abs max rating of…

  • Query about AD8497 Output

    Hi, there

    I have a question about AD8497. I used AD8497 for Type K thermocouple. I put thermocouple into the mixture of ice and water, which should be 0°C. However, the output of AD8497 shows it is 5°C. I tried with many temperature points. It shows…

  • Output range problem for AD8497

    Hi. I am using AD8497 for K-Type thermocouple measurement. I have given supply of +5v and 0V. and Ref voltage of +0.5V. My input signal ranges from -2.0mV to 70mV. I get output signal only for input signal upto 40mV. Please suggest schematic for measuring…

  • Thermocouple amplifiers AD8495/AD8497

    Hello sir/madam

    AD8495 has ambient temperature (reference junction) in the range of 0 Deg to 50 Deg

    AD8497 has ambient temperature (reference junction) in the range of 25 Deg to 100 Deg

    Please suggest any other thermocouple amplier which has ambient…

  • AD8497:negative temperature & unipolar supply.


    AD8495/AD8497: according to datasheet,

    'Reference pin voltage can be offset to measure 0°C on single supplies.'


    Is this also applicable for negative temperatures,

    i.e., is it possible to use unipolar positive power supply…

  • Slightly high voltage output on AD8497.

    I am trying to build a DIY reflow oven and have converted a small convection oven.  Since all thermocouple conditioner/ampflier IC's on the market are surface mount I have been kind of stuck, since I need to solder the IC, but can't solder the IC until…

  • AD8497 Setpoint controller has three states?

    Hello as part of my bachelorthesis i am working on a setpoint controller for the temperature. therefore i used the ad8497. But the amplifier is not working properly. Because the sensor has 3 states. One state for off which means 0V and one state for…

  • Looking for a PCB layout sample for AD8497

    I have looked all over the internet for a sample layout for ultiboard for the AD8497 Thermocouple. I am manufacturing the circuit for a class using the basic connection from the data sheet. (http://www.analog.com/static/imported-files/data_sheets/AD8494_8495_8496_8497…

  • 【问】一块板上用4个AD8497接4路热电偶测温, 如下电路图

    【问】我在一块板上用4个AD8497接4路热电偶测温,AD8497输出端是接到AD. 正常情况下如果我断开其中一路热电偶,其他三路的电压会有很大变化,这是为什么?
